摘要(Abstract):

对一新安装灯具的室外篮球场地照度进行了测量,发现该场地的水平照度均匀度仅为0.49,且眩光效应严重,照明效果不理想。在没法进行重新布灯的情况下,通过仅改变灯具的投射角进行照明设计,并用软件对篮球场的照度进行模拟。利用场地原装灯具非对称出光的特点,找到灯具的最佳投射点来调整了各灯具的投射角度。经过软件模拟后,场地的照度均匀度为0.70,比实测的0.49有很大的提高。统一眩光值小于10,说明有针对性地改变灯具的朝向会大大降低光源正对人眼的概率。本文给出的灯具投射角度调整方案,对篮球场照明现场调光具有参考价值。
The illumination of the outdoor basketball court with newly installed lamps was measured. It was found that the horizontal illumination uniformity of the court was only 0.49, and the glare effect was serious. The overall lighting effect was not good. In this case, it is impossible to rearrange the lamp, therefore the lighting design is carried out by only changing the projection angle of the lamp, and the illumination of the basketball court was calculated with software. By using the characteristic of asymmetric light emission, the best projection point is found to adjust the angle of each luminaire. After software simulation, the uniformity of site illumination is 0.70, which is greatly improved compared with 0.49 measured. The uniform glare value is less than 10, which can meet the illumination value of the sports lighting. This article gives the lamp projection angle adjustment lighting optimization plan, which is instructive to the scene dimming.
